4.5
The point of time when mode settings are detected and executed differs with the mode
register type. Two different behaviors can be classified:
• evaluation and execution after SW-reset (C/I= RES) or upon transition out of state
• immediate evaluation and execution
Below the mode registers are listed and grouped according to the different evaluation
times as stated above.
